18 Claims. (Cl. 189-46) This invention relates to a car door construction and concerns itself with means for sealing the perimeter of the door against the weather when the same is in closed position and in which a portion of the sealing means serves as a latch invention, and illustrating adjacent parts of the car.

Figure 2 is an enlarged and broken sectional view taken upon the line II-II of Figure 1, the door being shown in partly open position and the rollers Shaving passed out of the depressed portions of the track.

Figure 3 is an enlarged sectional view taken upon the line 1IIIII of Figure 1, looking in the direction of the arrows.

Figure 4 is an enlarged sectional view taken upon the line IV-IV of Figure 1, looking in the direction of the arrows.

Figure 5 is an enlarged fragmentary elevational view illustrating certain features.

Figure 6 is an enlarged sectional view through the locking means for the door.

As illustrative of thisinvention, there is shown a house car door 1 having a Z-bar 2 extending along the upper margin. The web of the Z-bar is attached to the door with one flange 3 (Fig. 2), extending inwardly over the top thereof, and the other flange 4 extending outwardly. A pair of rollers 5 are mounted upon suitable journals 6 supported by the Z-bar 2, the outer flange of which is coped or cut out to allow the rollers to extend therethrough asvshown in Figure 2.

The rollers 5 are adapted for traveling upon a track '7 formed upon a plate or housing 8 which encloses the rollers and which is attached to the side plate 9 of the car. It will be noted that the side plate 9 is in the form of a Z-bar having a depending flange 9a which cooperates with the flange 3 on the Z-bar 2 for excluding the weather. Further, as the rollers 5 fit quite closely in the copes of the flange 4 of the Z-bar 2, the weather is also excluded by the flange 4 of the Z-bar 2, so that adouble seal against the weather is obtained. The aforementioned track 7 is provided with a pair of depressions 10 to receive the rollers when the door is in closed position. These depressions slope inwardly toward the car as shown in Figure 2, so that there will be a tendency to move the door inwardly when the rollers drop into the depressions 10.

Upon the side sill of the car, there are secured angle clips 11 to which a weather strip 12 in the form of an angle is secured. This angle has one flange secured to the outstanding flange of the angle 11, while the other flange is directed upwardly and is deformed to provide an upwardly and outwardly sloping surface 13.

Along the lower margin of the door, there is secured a longitudinally extending member or plate 14 having an inwardly offset sloping portion 15, the outer surface of which slopes downwardly and inwardly for cooperating with the sloping surface 13 on the angle member 12. With this construction, it will be obvious that when the door is closed and the rollers drop in the depressions 10, the door will drop downwardly a distance equal to the depth of the depressions, with the result that the sloping surfaces on the members 12 and 14 will force the door inwardly as the member 14 slides downwardly past the member 12. It will be obvious that the contacting members 12 and 14 will exclude the weather. Further, a threshold plate 16 is attached to the floor of the car and extends downwardly over the edge thereof, and is attached to the side sill as indicated at 1'7. When the door is tightly closed it will press against the threshold plate and also tend to exclude the weather. Accordingly, the top and the bottom of the door are protected by a double seal.

Upon the rear door post 18 (Fig. 3), there is a vertically extending weather strip 19 which is in the form of an angle having one flange attached to the post 18 and the other flange directed rearwardly and deformed to provide a sloping surface 20. Upon the rear inner edge of the door, there is a vertical weather strip 21 having a sloping surface in engagement with the sloping surface 20. These sloping surfaces are so directed that they draw the door inwardly when the door is closed and the same are brought into sliding engagement.

Upon the front margin of the door, there is secured a vertical weather strip 22 (Fig. 4) which is in the form of an angle bar having its outstanding flange rearwardly bent as indicated at 23. Upon the front door post 24, there is secured a vertical angle bar 25 having an outstanding flange against which the weather angle 22 is designed to abut to exclude the weather.

Suitable hinge members 26 are secured to the angle 25, and a vertical weather sealing and door locking plate 27 is hinged to the hinge members 26 as indicated at 28 so that it can-turn or swing.

This plate 27 is provided with a vertically extending groove 27a for receiving the outer edge of the weather strip 22 and beyond this groove, said weather plate 27 is inwardly directed in the form of a bend 27b beyond the outer edge of the weather strip 22 to provide a shoulder or abutment in front of the outstanding flange of such weather strip 22 whereby the door is locked or latched against sliding movement when the locking weather strip 2'7 is in its operative position. Should the sealing and locking plate be in operative position when the door is open, it will not prevent the closing of the door since the weather angle 22 on the door will swing the plate 27 outwardly when it comes in contact therewith due to the contours of the two parts.

Means are provided for locking the sealing plate 27 in its operative position and in the form shown, this means consists of a latch lever 29 which is pivoted intermediate its ends to a bracket 30 attached to and extending from the side of the car. When the latch lever is swung into horizontal position as shown, its forward end 29a will engage over the sealing plate 27 and prevent the same from swinging on its hinges. In order to maintain the latch lever 29 in its operative position; a latch hook 31 is pivoted between a pair of ears 32 on the bracket and is adapted to swing downwardly so that its hooked portion will engage under the lever. The bracket 30 is provided with a lug 33 (Fig.4). The lug 33 and latch hook 31 have registering apertures 34 for receiving a sealing ribbon when the latch hook is in its operative po-' sition whereby the door may be sealed. The latch hook 31 is adapted to swing upwardly torelease the latch lever 29 so that the same may be swung into dotted line position as shown in Figure 5, and allow the sealing plate 27 to swing outwardly to release the door.

It should be noted that the door is entirely devoid of fixtures except the rollers, and for this reason it is possible to widen the car and still maintain the proper tunnel clearances. At the sametime, the perimeter of the door is effectively sealed from the' weather when the door is closed. It will also be appreciated that by housing the rollers, as herein set forth, it will be impossible for matter to accumulate upon the track and block the sliding movements of the door. The novel feature of the sealing plate 27 that engages the front edge weather strip on the door avoids the use of 1 extra locking latches for securing the door and so performs a two-fold function.

We are aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
